MODE OF VENTILATING GRAIN.

Specication forming part of Letters Patent N0. 511.969, dated May 22,1866.

To all whom it may concern:

Be it known that I, JOHN SHONE, of Blackwoodtown, iu the county ofCamden and State ot'New Jersey, have invented a new and Improved Mode ofVentilating Grain; and I do hereby declare that the following is afull,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, in which- Figure lis a plan or top view of the improvedbin with the covers F F thrown up for the purpose of showing theinterior arrangement of the bin. Fig. 2 is a vertical section of thesame at the red line 1 2 of Fig. 1. Fig. 3 is a view of the verticaltubes C and G and horizontal tubes H in connection in an invertedposition. Fig. 4 isa perspective view of one of the vertical tubes lLinverted.

Like letters in all the figures indicate the same parts.

Thenature of my invention consists of a perforated bottom and series ofperforated tubes for expelling the heat which arises from grain whenstored in bins, constructed and arranged substantially as follows.

A is the body ofthe bin. B is the bottom, which is represented ofsheet-iron perforated to allow the cold air to circulate through thegrain, it being elevated by means of the legs a.. I usually constructthe bottom, however, of wood with large holes at suitable distancesapart, which I cover with perforated metallic plates, the bottom beingwell supported by strong bars beneath it, secured at their ends toparallel sides of the bin.

C C are perforated tubes, which are connected with the bottom at theirlower ends by means of the hollow metallic studs D D, which are madefast to the bottom. These tubes have protecting cap-pieces O', whichextend above the top of the bin; Theirlower ends fit in correspondingholes in the cross piece E, which has rabbets b for the support oftheinner edges of the covers F F. The said cappieces have large openings c,to allow the heated air as it passes into the main and'conductig tubes(l to flow freely out of the same.

With the tubes G, I combine other vertical perforated tubes, G, andhorizontal perforated tubes H, having a sufficient number throughout thebin to carry off all of the heated air.

The tubes should be open at their lower ends l to effect a freedischarge of the dust which passes into them through the perforations.The horizontal tubes H have slots in their under sides, as seen in Fig.3, for the same purpose.

There are vertical perforated tubes I I for carrying off the heated airat the sides of the bin. I have represented but two; but in practicaloperation there should be several on each side. These tubes are open onthe side next the side of the bin, and have anges d., which are securedto the bin by means of screws or or tacks. i

There are openings e in the front sides of the studs D, which allow thedust which may pass through the perforations into the tubes G to escapeas the grain is drawn out of the bin from the bottom of the same bymeans of the chute J. K is a gate for closing the chute.

For the purpose of a uniform discharge of the grain throughout its wholearea, I make the bottom B to descend from the back and ends of the binto the chute J, as represented in the drawings.

There are grooves f in the undersides of the covers F F for the exit ofheated air. Instead of making them in the covers they may be made on theedges of the bin, if desired.

I provide for the discharge of the grain from the bottom of the bin, asabove described, for the purpose of agitating the grain throughout theentire mass to enliven it, which is prevented by taking ont from the topof the bin in the usual way. i

The operation is as follows: As the grain commences heating the cold airpasses up from beneath the bin into the body of the same, through` theperforations in the bottom B, and expels the hot air through theperforations in the series of tubes above described, and -by means ofthe exit-openings c of the cap-pieces C' it is drawn into the main tubesC, and passes up the same and escapes through the exitopen ings c, whichoperation continues while the grain is in a heated state.

Bins constructed in the usual manner may have my improvement attached tothem by altering the bottom to conform to the abovedescription. asdescribed for this purpose there may be a suitable number of tubes L,(see Fig. 4,) which I make pointed at one end for the purpose of Insteadof constructing the tubes running them down into the body of the grainthe main tubes C, substantially in the manner in bins already lled. andfor thepurpose specified.

Having thus fully described my improved 3.
